placed thereon and closed by the springs.

, panying drawings With this object in View, the lid closing springs can be adjusted to different distances from the base plate or plates supporting the cans.

To illustrate the invent-ion, several 2 examples thereof have been described hereinafter, reference being had to the accomforming a part of this specification.

In said drawings, Figure 1, is a side view of the apparatus partly in section, Fig. 2, is a horizontal cross-section of Fig. 1 taken on the line A, Fig. 3, is a detail view showing a spring for holding the lid in closed position, Fig. 4, is a side View similar to that of Fig. 1, to illustrate a modification of the apparatus, Fig. 5, is a horizontal crosssection of Fig. 4 taken on the line B, Figs.

6 to 8, are detail views showing modifications of the springs for holding the lids in closed position, and Fig. 9, is a perspective view of one of the adjustable base plates.

On a horizontal base plate 1 a hollow pil-' The construction of the springs appears from Figs. 1 to 4. As shown in those figures, a leaf spring 4 is bent upward at one of its ends'to form a shank '5. To thesame end a flanged piece 6 is secured having .its flange directed downward and arranged at a certain distance from the shank 5. If it is desired to secure the spring to the pillar 2, the flanged piece 6 is inserted into one of the slots 3, as appears from Fig. 2. In

the preferred construction the height of the flange of the piece 6 is equal to or slightly less than the breadth of the slots 3. As

"shown in Fig. 2, the spring is turned sidewise while being inserted, whereupon it is turned at an angle of so as to assume its normal position. In the regular position of the spring, its shank 5 bears against the outside of the pillar, while the flange of the piece 6 bears against the inner side of thesame. As shown in Fig. 1. both shanks are broader than the slots 3. If now the springs 4 are pushed downward and on the lids 7 of the cans 8,. they are clamped on the pillar by means of the projecting shank 5 and the flange of the piece 6, and they eX- ert a pressure on the lids which is so much the stronger the more the springs have been pressed downward and on the lids. In some cases it may be desirable to permit the springs 4 to be turned sidewise and out of the radial position relatively to the pillar 2.

freely turned about its pivot, its shank 5 is rounded as shown in Fig. 2. When using springs which can be turned in the manner described, the can closing pressure of the springs can be applied to any point of the circle inclosed by the springs.

In the modification illustrated in Fig. 6, the spring 4? consists of a strong wire the shank of which extends through a T-shaped eye 19. The latter may also be made of wire, and the projecting shank of the spring is enlarged in a suitable way as shown at 20. The eye 19 of the spring is inserted into the slot of the pillar in the same way as before described, so that the lateral projections of the eye bear against the inner surface of the pillar, while the enlarged portion 20 thereof bears against the outer side. Preferably the lateral shanks of the eye 19 are bent downward, so that the eye is more rigidly clamped against the pillar.

In the example shown in Fig. 7, the leaf spring 4 is secured to a plate 21 having a shank 22 projecting upward therefrom and a lip 23 projecting outward. The latter is made with a pair of notches 24 adjoining the shank 22. By means of the plate 21 and the notches 24 the spring is held within the slots 3 of the pillar 2. In the example illustrated, the spring is pivotally secured to the plate 21 by means of a pivot bolt 25, and the end of the leaf spring adjoining the shank 22 is rounded concentrically to the pivot bolt 25. The shank 22 of the plate 21 is formed with a nose 26 projecting into the slot 3 of the pillar 2 when in operative position. By the said nose the spring is prevented from being tilted about its longitudinal axis. Therefore, the nose 26 is particularly adapted for use in springs which are. pivotally mounted on their supporting plates, which otherwise are subject to being tilted sidewise, if they are turned out of their radial positions. Evidently a nose of this character may also be provided in the example illustrated in Fig. 3.

A further modification of the spring is shown in Fig. 8, in which the spring P is formed, at its rear end, with a shank 5 similar to that described with reference to Fig. 3, and it is secured to a plate 21 which is formed with a lip 23 projecting rearward and having a pair of notches 24?. To enable a plurality of cans to be placed one above the other, adjustable base-plates or shelves 10 may be provided on the pillar 2, as shown in Figs. 1 and 5. The said shelves are supported on the pillar in the same way as the lid holding springs. For this purpose, the shelf 10 is made integral with an arm 11 having a shank 12 projecting upward there from, and a flanged piece 13 secured thereto and projecting with its flange downward. Vith the shanks 12, the plates are inserted into the slots 3 of the pillar 2 in the same way as the lid holding springs, and they are clamped thereon by being turned into their normal positions, as will readily be understood from the description given with reference to Fig. 2. Preferably, the plates are provided with marginal flanges 14 whereby the cans placed thereon are prevented from sliding off.

A further example of an adjustable shelf is shown in Fig. 9. As shown in the said figure, the arm 11 of the shelf is secured to a supporting plate 26 having a flange 27 projecting downward and a horizontal lip 28 projecting beyond the latter. By means ofthe lip 28 the plate 26 can be inserted into and clamped to the slots 3 of the pillar 2. For this purpose, the lip is formed with a pair of notches adjoining the shank 27, and engaged by the wall of the pillar 2 when inserted into the slots 3. The base plate 10 and its arm 11 may be pivotally or rigidly secured to the supporting plate 26 In the example illustrated, it is connected thereto by means of a pivot bolt 29, and the end of the arm 11 engaging the plate 26 is rounded. The shank 27 of the supporting plate 26 is provided with a nose 3O engaging the slot 3 of the pillar 2 when brought in position, and thereby preventing the plate from tilting. In a similar way, a nose may be provided in case of the adjustable base plate illustrated in Fig. at.

In the example illustrated in Fig. 4, two cans are placed one above the other. But it should be understood, that any suitable number of cans can thus be placed one above the other, according to the height of the pil lar and that of the cans. Instead of providing a separate adjustable base plate 10 for each of the cans, a common shelf made of two sections may be provided for all the cans disposed in the elevated position. hen thus using a common shelf for all the cans, the cans can be more advantageously distributed, and a greater number of cans be placed on the shelf, than in case of separate shelves for each of the cans. However, cans of different heights can not be arranged on the same base plate.

In the example illustrated in Figs. 4c and 5, the shelf 15 consists of two sections, one of which is shown in the figures. Each of the said sections is provided, at its bottom face, with a semi-circular flanged disk 16, embracing one half of the pillar, and at its top face it is provided with a flanged disk 17 having at its free end an upwardly extending section 17 By means of the latter, each section is inserted into one of the slots 8. Each of the sections of the shelf bears with its flanged disk 16 against the outer face of the pillar, and with its flanged disk 17 against the inner face of the same, and it is clamped thereto in the same way, as the shelves 10 or the lid holding springs, as soon as it is weighted by the cans placed thereon. 'Therefore it provides a reliable support for the said cans.

I claim:

1. In a sterilizing apparatus, the combination with a can support and a vertical tubular upright or pillar, having therein a plurality of longitudinally extending slots, and a plurality of resilient arms, each having a section extending through one of said slots and projections extending into contact with opposite faces of the wall in which said slot is formed, each of said arms being adapted to contact with the top of a can placed on the can support.

2. In a sterilizing apparatus, the combination with a can support and a vertical upright or pillar, of a resilient arm, comprising two members, pivotally connected, one of said members engaging the upright or pillar and the other member being adapted to engage the top of a can placed on the can support, the pivoted connection between said members permitting the latter to be turned at any angle to the former to properly engage the can top.

8. In a sterilizing apparatus, the combination with a can support and a vertical tubular upright or pillar, having a longitudinally extending slot formed therein, of a resilient arm including two members pivotally connected together, one of said members extending through said slot in the pillar, and having projectionsextending into contact with opposite faces of the wall in which said slot is formed, and-the other adapted to contact with the top of a can placed on the can support 4. In a sterilizing apparatus, the combination with a pillar having therein a longitudinal slot, of a can support having clamping means'adapted to engage said slot and to secure the support at different parts of the slot, a nose on said can support extending into the slot in the pillar, and a spring adapted to engage the lid of a can placed on said support.

5. In a sterilizing apparatus, the combination with a can support, of a pillar having a longitudinal slot providing inner shoulders, and a spring adapted to engage the lid of a can placed on said support and having clamping means adapted to bear against the inner shoulders and the outer margins provided by the slot in the pillar, and a nose extending into the slot.
